Input this instruction, allowing the AI to complete the entire process step-by-step: extracting selling points, determining style, determining layout, and finally generating a complete, system-wide prompt.

Creative, realistic and surreal advertising design for a product {argument name="product_name" default="[product name]"} from the category {argument name="product_type" default="[product type]"}, where the product appears as a heroic element in the center of the frame and visually forms in a smart way that automatically reflects the spirit and identity of the brand. A clean background that matches the brand colors, soft cinematic lighting, ultra-realistic materials, precise shadows, and strong visual composition.
